Okay 2 ways for the friction to increase is speed and non lubricant
Rougher surface and more weight to the object increases friction
Friction between two surfaces can increase due to an increase in the roughness of the surfaces or an increase in the normal force pressing the surfaces together. Additionally, an increase in the surface area of contact between the surfaces can also lead to an increase in friction.
Polish the interacting surfaces or decrease the normal force acting on the moving object.
There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.
1)increasing the roughness of the surface 2)increasing the mass of the object
You can increase friction by increasing the roughness of a surface or by increasing the force pushing the surfaces together. You can decrease friction by using lubricants or reducing the contact area between the surfaces.
one way is to make the surface rougher and another way is to increase the force pushing the surfaces together.

To increase friction, you can use materials with rough surfaces, increase the force pushing the objects together, or increase the surface area in contact with each other. To reduce friction, you can use lubricants like oil or grease, make the surfaces smoother, or incorporate bearings or wheels to minimize direct surface contact.
Friction can be increased by increasing the roughness of the surfaces in contact, increasing the force pressing the surfaces together, or using materials with higher coefficients of friction. Additionally, increasing the surface area in contact can also increase friction.
find a materials with a high coefficient of static friction and use them against each other ( like rubber dry concrete ) and bound them to the object and the surface it rests on. Increase the normal force by adding mass on the object or applying a perpendicular force to the surface of the object.
